Using Service Clients

AWS service client classes provide you with an interface to the AWS service that the
class
represents. Service clients follow the namespace convention Aws::Service::ServiceClient.

For example, a client for AWS Identity and Access Management is constructed using
the Aws::IAM::IAMClient class.
For an Amazon Simple Storage Service client, use Aws::S3::S3Client.

When you use the client classes to instantiate a service client, you must supply AWS
credentials.
You can do this by using the default credential provider chain, by manually passing
credentials to
the client directly, or by using a custom credentials provider.
